engine noise

have a 2.4 dual overhead cam engine that has developed an engineknock or rapping sound have gotten opinions on what its is from timing chain slapping , rod knock, bad lifter ,

i think it may be a bad lifter ,how do i go about finding what is really making the noise engine has 84,956 miles on it

unfortanely ur gonna have to get to the root of it. which usually mean tear it down and hope u find it. it could be one of everything you metioned or it could be a valve that needs to be tightened, but if i had to guess id say bad lifter.

thanks for the reply i almost have the engine apart as soon as i crack loose the crankshaft bolt iwill be able to evalueate the timing chain and then i will remove cam carriers and the head.-

I had a friend with the same problem. He decided to just drive it til it dies.

It never died.
